Hopper Dispense Rate of Product

The hopper dispense rates are preset at the factory. With 22 tooth gear and auger wire, the preset dispense rate is approximately 3 to 5 grams per second. With 30 tooth gear and auger wire, the preset dispense rate is approximately 5 to 7 grams per second. The hopper dispense rates can be individually programmed to a range of dispense rates from approximately 1.5 to 12 grams per second, by following the procedures described in Programming Modes.

HOPPER LEVEL SENSOR CALIBRATION

The dispenser is equipped with sensors to detect a low level in each hopper. When low powder lockout is enabled, dispensing will be disabled when a low powder condition is detected in a hopper. The LCD screen on the door will also display a low level condition.

The despenser is shipped from the factory with the low level powder lock disabled. To enable the lock, place the “NORMAL/PROGRAM/RINSE” switch (page 10) in the “PROGRAM” position. Press button A (page

10)below the BUNN logo on the front of the door. Continue to press this button until the “LOCKS/DISABLES?” menu is reached. Press button B (page 10} for “YES”, then press it again in the “LOW POWDER LOCK?” menu. The low powder lockout is now enabled. Press button C (page 10) to exit the program menus, then return the “NORMAL/PROGRAM/RINSE” button to the “NORMAL” position. To disable the low powder lockout, repeat the process, and press button D (page 10) for “NO”, in the “LOW POWDER LOCK” menu.

The low level sensors are factory calibrated for most products. If calibration is required for proper opera- tion, the sensors can be recalibrated to the current product.

The hopper must be at least half full of product for calibration. Place the “NORMAL/PROGRAM/RINSE” switch in the “PROGRAM” position. Using button A (page 10), forward until the “CALIBRATION?” menu is reached. Press button B (page 10) for “YES”, then press button A (page 10) until “CAL HOPPER 1?” screen is reached. Continue to press button A until the hopper to be calibrated is reached.

To calibrate the hopper, press button B (page 10) to indicate “YES” in the “CAL HOPPER#? screen. The screen will then ask you if the hopper is full. Press the button again to indicate “YES”. The calibration will then take a few moments, then the screen will display “POWDER LEVEL RESET COMPLETE”. The next hopper may be calibrated by moving forward in the menu, or press button C (page 10) to exit.
